By the alkaline earth h droxides are meant the hydroxides of such as calcium, barium, strontium or ma nesium But more particuar y 0 calcium as that element seems to give best results when in its hydroxide state. It is to be understood that the oxides of such substances are within the purview of my disclosure, as the oxides when used in the presence of water will generally be changed to hydroxides.- Further, the oxides or the hydroxides may be the natural-earthy sub-. stances or they may be the product of chemical processes as for instance the reci ita-tion of calcium hydroxide from other calcium compoun e a aline hydroxides as produced-from calcined marine shells or bon materials maya 0 e a van ageo yutllized in my invention.

Watersoluble silicates may be added to the aqueous dispersion, hut in doing so care should be taken to avoid curdling or precipitation on the addition of the earth hydroxide or the boron compound. If this curdling is undesirable it may be avoided by first making up the composition with a water-soluble colloid thatis compatible to the alkaline earth hydroxide and the boron compound. The water-soluble silicate such as sodium silicate may then be cautiously added, 1f not 1n too large amounts, and the curdling avoided. A
